Soon Thunder?  I would have thought that stage has well and truly arrived with the debacle with Paul Gee.  If I had any of my staff being audited I would not for one minute leave them alone with the auditor - and that's not becasue I think any of them do not do their work 100% correctly, it's because I don't trust the PGDB in any way, shape or form.  The evidence is there for all to see - 44 particulars of bollocks for Paul Gee and the poor bugger has been roasted - and when the charges fall over and over and over - do they apologise, do they say - hell we made a massive cock up on that one - no.  Their investigative procedures and processes are sloppy to say the least and no one wants to be caught up in three years of hell.
Have you learned lessons only of those who admired you, and were tender with you, and stood aside for you?  Have you not learned great lessons from those who braced themselves against you, and disputed the passage with you?  (Walt Whitman 1819-1891)  American Poet

hi all, well my audit went well, the guy was very informative and explained why i was the case of a random audit. we discussed a number of issues and i said to him why the hell isn't the board communicating with EVERYONE about these issues!!
in all i was pleased with the format of the aduit.
ps. the board reads this forum ;)
I believe in doing a job once and right. !

we all know the board reads this form as there trying to gauge what is happening out there and ways to counter any possible action funny how they were running at a defficit and as soon as we mention that we could all refuse to pay our fees to send them bankrupt it is very funny how all of a sudden they mannage to run at a surplus and have a nice little piggy bank stash of our money sitting there waiting for such an event!...were not stupid we can see whats happening even without knowing whats happening...so why should a charity run a surplus of funds??? is my question?

Can someone confirm my take on it. There is a small clause in there under the diagram in 2.4.5.9
"does not apply to a breather vent" or similar wording....
Which rules out all of the domestic lpg changeover systems that I come into contact with.

Thoughts anyone?

hi 07442, i would bet the board would say that's a regulator classed as a non ventilating type

dont you mean 2.5.4.9  :P i was looking for 2.4.5.9 for a while quite perplexed as to where it was.... then it dawned on me  ;D
by this do they mean the pin hole driphram breather vent much the same as the pin hole breather vent on a prv to allow the non working side if the driphram to vent to atmosphere to allow correct movement of said diaphram allowing correct working working of valve?

Yes. My mistake. Transposed the numbers , the clause is there - breather reglators are excluded, only applies to a venting regulator.

This is purely my opinion on my interpretation of the code. The PGDB probably have some sick twisted interpretation of the same thing, so they can persecute me into bankruptcy.

this is my ten cents, isn't it about time that venting regulators where band ? they are dangerous! make all regulators non venting fail safe. end of story???? like tempering valves!!! its not rocket science !
designed to lock out when the out let pressure exceed 7 kpa....what do you think?
realistly, when a regulator vents the gas disperses and the further away form the vent the lower the fuel to air ratio is....
which equates to less chance of ignition....
Then we have 5261. and the boards interpretion of it! !  !  ??? a air intake has been taken way beyond what the team of people that wrote nzs5361 believed it would.  and then there is clearance from a opening into a building that they have interpreted too !!!
i power flued water heater can be mounted 300 mm to the side of a window......so why not under it????or above it ????? what is the difference???? ....answer... there is NO difference, full stop. and all of you practicing gas fitters know it.
fact!
1 the unit mounts on the wall out from the window/ door.
2 power flue expels the products of combustion away from the building and the opening too that building.
3 the products are then diluted by mixing with air by means of the fan force and with heat of the products including water vapour .
4 why doesnt the pgdb listen to the ones who know what they are doing????
..... 8)my ten cents....again.
AND what can be done about this??????

hi guys/Bowtieboy,you say:(i power flued water heater can be mounted 300 mm to the side of a window)
 That is only if the unit is 200m/j or less otherwise it is 1500mm.  Rheem have on special at Micos a 27ltr unit at the moment  that is 205mj per hr, don`t get caught out and fit them to close.  Most of the places that i fit w/heates to do not have enough space between windows to use them,cheers

yes great stuff Robbo,
 but according to pgdb, meter clearances are NOT gas fitting in the context of nzs5261, and the same goes for lpg bottle location, check nzs5261, the info on bottle location is informative only!!.
that's where i had come unstuck. you would think if a vent on a meter regulator is ok to be that close to an ignition source, that it would INCLUDE a gas appliance, the board think otherwise!
very miss leading and i believe its wrong. if a regulator vents, there must be a determind safe zone that works across the board. and why the hell didn't the people that wrote the standard get it right and consistant.instead they just copied another standard nearly word for word...very disappointing. :-X

Why don't you ask one of the Investigators or the ESS for a ruling/advice.....they are the ones to enforce it after the install, get them to put in their 2 cents worth before .....goodluck.
You can't choose who you are.....but you are the sum of your choices.......
